Title: Motor operated focusing device
Inventor: SHIOGAMA YOSHIHARU
IPC: G02B7/28
Filed: 1990-08-08
Abstract: PURPOSE:To rapidly make an exact focusing operation by electrically detecting the operation of a manual operating member, such as power focus switch, and moving a lens group by the motor driving corresponding to this operation, thereby making the focusing action. CONSTITUTION:The power focus switch 39 including an operating knob 39A transmits an instruction signal to a main CPU 31 when an operating knob 39A is operated in a 'infinity ' direction or 'very close' direction. The CPU 31 transmits the driving control signal of a motor 43 for lens driving to a driver circuit 41 in accordance with the aperture value data Fs from an AE controlled CPU 33 and the instruction from the switch 39. The circuit 41 controls the drive of the motor 43. An encoder plate 47 having a slit-like light transparent part for detecting motor revolution is provided on a motor shaft and generates, together with a photointerrutor 45, the feedback pulses indicating the rotating quantity of the motor. These pulses are transmitted to the CPU 31. Since the micro-driving quantity at the time of fine adjustment focusing is corresponded to the aperture value set at the time of photographing, the adequate micro- driving quantity is set even in a zoom lens.

Title: Unidirectional shaft seal device
Inventor: IWAMOTO SHOICHI
IPC: F16J15/46
Filed: 1989-08-16
Abstract: PURPOSE:To improve efficiency by a method wherein the flow of fluid from the one to the other of two spaces formed in a partitioned state on both sides of a unidirectional shaft seal device located between actuator and the outer peripheral surface of a shaft is suppressed, and a flow in a reverse direction is facilitated. CONSTITUTION:When a pressure Pc in an internal space C of an actuator is in a Pc > Pe state in which it is higher than a pressure Pe in an external space E of the actuator, a pair of seal rings 3 are moved within a peripheral groove 2a in a direction reverse to a notch 4a by means of the pressure Pc, and forced into contact with the other peripheral side surface 21a on the opposite side to the notch 4a. In this case, fluid in the space C flows through a gap 11 between the seal ring 3 and the peripheral groove 2a and flows through the notch 4a of a resilient ring 4. On the outer periphery of the seal ring 3, the fluid is worked as fluid having the pressure Pc reduced due to lowering of a pressure. This constitution forces the inner peripheral surface of the ring 4 into pressure contact with the outer peripheral surface with a high force, and forces the inner peripheral surface of the seal ring 3 into slide contact with the outer peripheral surface of a shaft 1 with a high force.

Title: Manufacture of twin-core parallel cable
Inventor: OTA AKITSUGU
IPC: H01B13/00
Filed: 1990-08-10
Abstract: PURPOSE:To regulate the tensions of two core wires in a good balance when an insulating sheath is extruded, and to obtain a parallel cable of a good quality, by covering with the insulating sheath after holding the two core wires integrally by applying a glass rim type insulating coverage. CONSTITUTION:In order to hold two core wires 12 and 12' parallel and to insulate them, the conductors 12a and 12'a of the core wires 12 and 12' are held integrally by a glass rim type insulating coverage 16, and after that, an insulating sheath 14 is applied as a coverage on the glass rim type insulating coverage 16. By insulating the two core wires 12 and 12' with the glass rim type insulating coverage 16 integrally in such a way, the core wires 12 and 12' are never loosened by the coverage 16. And since the two core wires 12 and 12' are arranged parallel in a good balance by the glass rim type insulating coverage 16 prior to the extrusion of the insulating sheath, the regulation of the tension is made unnecessary.

Wide visual field targets are presented to the subject S from optically apparently far positions, and the right and left wide visual field targets are both projected to the center of the visual field of the subject S. Since the subject S views not a blurred target but the clear target 21, the diopter is induced by fog and adjustments can be remitted.

Title: Manufacture of resin sealed semiconductor device
Inventor: SASAKI MUTSUMI
IPC: H01L21/56
Filed: 1992-07-15
Abstract: PURPOSE:To make thin burrs of a resin, generated during the course of a resin sealing process, not to fall down until a semiconductor device is set to a resin burr removing process so as to prevent the environment from getting worse and the burrs from obstructing the transportation of lead frames after sealing the device with the resin by making the resin to flow out into a space surrounded by a package and the lead frame by a fixed amount. CONSTITUTION:A resin sealed semiconductor device is manufactured in such a way that a lead frame 2 mounted with semiconductor elements is set in a resin sealing mold composed of a top force and bottom force and the mold is filled with a resin 3 after the top force is put on the bottom force. A recessed section is provided to either the top force or bottom force so that a gap having a fixed thickness can be formed in the section surrounded by the frame 2 and packages 1 when the top force is put on the bottom force so that the resin 3 can flow out by a fixed thickness. For example, the recessed section is provided in the resin sealing mold so that formed resin burrs 3 can have thicknesses of about 0.2mm at which the burrs do not fall down until the package is sent to a resin burr removing process after the resin sealing process and can be easily removed by means of a resin burr removing mold.

Title: GaN CRYSTAL FILM, AND III-FAMILY ELEMENT NITRIDE SEMICONDUCTOR WAFER AND ITS MANUFACTURE
Inventor: USUI AKIRA
IPC: H01L21/205
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To reduce distortion, defects, and transformation even in the case of formation on substrates with different lattice constants and thermal coefficients of expansion, by propagating the transformation being propagated in nearly parallel with a substrate surface in nearly the normal direction of the substrate surface near a part where a crystal is combined on a mask. SOLUTION: A GaN crystal is subjected to epitaxial growth for a growth region 3. The GaN crystal cannot be grown on a mask 4 at an initial stage, crystal growth occurs only at the growth region 3, and a facet 6 with an orientation that differs from that of the substrate 1 is formed at the GaN crystal on the growth region. Further, when epitaxial growth continues, the GaN crystal grows in a direction vertical to the facet surface, so that not only the growth region but also the mask 4 is covered, thus coming into contact with the facet of the GaN crystal at an adjacent growth region. Further, when the epitaxial growth continues, the facet is buried, thus finally obtaining a GaN crystal film 5 with a flat surface.

IPC: F02B27/02
Filed: 1986-09-08
Abstract: PURPOSE:To make the distribution of intake air uniform by providing a space part which is connected to each opening on the opposite side of the outlet port of a case for housing a rotary valve, in an engine in which the center hole of said cylindrical rotary valve provided in an intake passage serves as an intake air distributing part. CONSTITUTION:A rotary valve 11 which is rotated synchronized with the rotation of a crankshaft is provided on an intake passage 6. The valve body 14 of the rotary valve 11 has a cylindrical form and one end of the valve body 14 is opened and connected to the upper course side of the intake passage 6. An intake air flow is distributed within the valve body 14 and taken into each cylinder from each opening 15. Since the positions of the openings 15 are not uniform in relation to the flow in of intake air into the valve body 14, the intake air into each cylinder is liable to be nonuniform. However, a space part 22 is provided on the opposite side of outlet ports 21 on the outer periphery of the valve body 14 and, since the space part 22 is commonly provided to each of cylinders, the intake air which is taken in from the inside of the valve body 14 into each cylinder becomes uniform.
